Patent number: 9042224Abstract: A system for scheduling data for transmission in a communication network includes a credit distributor and a transmit selector. The communication network includes a plurality of children. The transmit selector is communicatively coupled to the credit distributor. The credit distributor operates to grant credits to at least one of eligible children and children having a negative credit count. Each credit is redeemable for data transmission. The credit distributor further operates to affect fairness between children with ratios of granted credits, maintain a credit balance representing a total amount of undistributed credits available, and deduct the granted credits from the credit balance. The transmit selector operates to select at least one eligible and enabled child for dequeuing, bias selection of the eligible and enabled child to an eligible and enabled child with positive credits, and add credits to the credit balance corresponding to an amount of data selected for dequeuing.Type: GrantFiled: December 2, 2013Date of Patent: May 26, 2015Assignee: RPX Clearinghouse LLCInventor: Bradley D.

Patent number: 8027346Abstract: A method and system schedule data for dequeuing in a communication network. The communication network includes an eligible scheduling node, a scheduling context structure, and an existence of data structure. In response to determining that an eligible scheduling node does not contain at least one child identifier in the scheduling context structure, an eligible child is selected for dequeue from the existence of data structure. At least one eligible child from the existence of data structure is absorbed into the scheduling context structure. The at least one eligible child includes the child selected for dequeue. Absorbing a child includes removing the child identifier from the existence of data queue and adding the child identifier to the scheduling context structure.Type: GrantFiled: May 29, 2008Date of Patent: September 27, 2011Assignee: Avaya Inc.Inventors: Bradley D.

Patent number: 7969884Abstract: A method and system for scheduling data dequeuing in a data communication network having a plurality of data queues and a hierarchical scheduler with a plurality of scheduling nodes. A determination is made as to which scheduler nodes and which data queues are eligible for dequeuing scheduling based upon at least one predetermined data rate limitation and availability of data at an eligible descendant node. Data is scheduled for transmission from one of the plurality of data queues. Scheduling data for transmission includes selecting one or more child scheduler nodes which are descendents of the one data queue but to whom the eligible child is not known to be eligible.Type: GrantFiled: May 9, 2008Date of Patent: June 28, 2011Assignee: Nortel Networks LimitedInventors: Bradley D. Venables, David G. Stuart

Patent number: 7814222Abstract: A system and method that includes monitoring a state of a physical queue receiving data is shown. The system and method includes generating, queuing, and scheduling messages based on the state of the physical queue, sending the messages to a virtual queue system, and approximating the state of the physical queue in a virtual queue system based on the messages. The system and method includes modifying a transmission rate towards the physical queue based on a state stored in the virtual queue system.Type: GrantFiled: December 19, 2003Date of Patent: October 12, 2010Assignee: Nortel Networks LimitedInventor: Bradley D.
